The TTI-LNB-Ka-1820 from TTI is a Low Noise Block (LNB) that converts an input frequency from 18.2 – 20.2 GHz to an output frequency from 1 – 2 GHz. It has a 17.2/18.2 GHz local oscillator. This LNB provides 60 dB of gain, image rejection of more than 30 dB, and a noise figure of less than 1.5 dB. It has spurious levels of -60 dBc and an SSB phase noise of -93 dBc (@ 100 kHz offset). The LNB requires a DC supply of 13/18 V and consumes less than 5 W of power. It is available in an enclosure that measures 150 x 60 x 40 mm with a WR-42 waveguide interface for input and N-type (female) connectors for output. It is ideal for satellite communications applications.
